In the interim meeting, the consensus was that we needed idr to be involved in 
any definition and solution for route leaks.  It was decided to discuss a 
message to the idr wg on the sidr list.

Brian Dickson has submitted drafts about route leaks, as he offered in the 
meeting.

So here is a first draft at a messate to idr.  Comments please.

==============

The sidr interim meeting in February discussed the problem of route leaks.

While those in the room could recognize route leaks in a diagram, they could 
not determine a way to determine that from information communicated in BGP.

Proposals to stop route leaks add information to BGP updates that would be used 
to restrict the propagation of those updates by the neighbor onward to 
providers, customers, peers, etc.

This is a change to BGP behavior, which now relies on local configuration only 
to choose a best path and advertise it.  Adding features to stop route leaks 
would restrict that advertisement and restrict what local policy could choose.

The consensus in the room was that adding a new feature to a protocol as part 
of a security protection  (i.e., not just ensuring an already defined behavior 
but producing brand new behavior) is unwise and leads to problems.

The sidr working group requests that idr discuss the route leaks problem with 
sidr and determine the best path forward.

The idr wg should also be aware that drafts have been submitted about route 
leaks, so work is underway.
